Dave, I'm not going to do that at this time. The wreck that I'm
getting the skin sample from doesn't have any riveted parts that are
so badly smunched that their removal would have zero impact.

If somebody out there does have a bit of flush-riveted Blanik wing
wreckage, I'd be glad to cross-section a couple of the rivets so we
can get an idea of the joint geometry.

Thanks, Bob K.
